-
- Linux is free. Linux is small. Linux has been fairly stable for quite some
- time, with new releases being almost entirely new features (Such as a modern
- VM, with unified buffer cache and user memory pool, extended / DOS
- file systems, etc). I first used Linux last November/Decemeber, and since then
- it's become quite stable.

- Minix also costs money. As it comes out of the box it can't run
- much of the freely available software, because of process size
- restrictions and the lack of VM.
-
- There are patches available that rectify this situation, but it won't
- be as clean, or easy, as starting with a real 32 bit VM OS from the
- start, like Linux.

- Coherent also sells for $99, and there's no way you'll get source code for it.
- While it is a 32 bit OS, it doesn't have VM.

-

-
- Linux is significantly more stable the the Jolitz port of BSD. Spend some
- time over in the comp.unix.bsd group, and you'll find a lengthy list of known
- bugs that MAY be fixed in the next release.
-
-
- BSD runs on less hardware than Linux - , Linux
- runs on IDE, RLL, MFM, ESDI, Adaptec 154x, 174x, Seagate, Ultrastor 14f, Future
- Domain 16 bit, and Western Digital 7000FASST SCSI disks, does enough 387
- emulation on hardware lacking a FPU to use a GCC with hardware floating
- point support, and has extended text mode support in the console driver
- for most SVGA boards plus CGA, MDA, Herc, EGA, and VGA.
-
- BSD also requires more resources than Linux - without Linux's
- shared libraries, X applications can grow from < 100K to > 400.
-
- Bill is also running a one man show - which makes it very difficult to get
- neat features into the kernel. On the otherhand, Linus will integrate
- any netter-contributions provided that there are clean context diffs
- and they fit cleanly into the Linux scheme of things. Consequently,
- Linux has lots of nifty features that BSD lacks, such as shared libraries,
- the MSDOS file system, virtual consoles that emulate VTxxx's, etc.

-
- It's smaller, has more features, runs on more hardware, consumes less
- resources, and is more stable.

- Microsoft is responsible for propogating the evils it calls DOS and Windows,

- Boycott AT&T for their absurd anti-BSDI lawsuit.
